Where did greek gods live?

I know that they lived аt the top of Olympus. But my question is if they were associated with planets how could they be humanlike? And again I know that not all ancient greeks believed that the planets are gods, but I read in the Wikipedia that italic peoples (such as Pythagoras) do believed. So how it can be combined?

Olympus could have been the mountain (ah, but which Mt. Olympus?) or the heavens; if Olympus is the sky above, it made sense to say - ah, that light there, that quick one? It's the messenger god Hermes (Mercury). It's not as simple as that of course because the planets are also supposed to be the children of Eos (the Dawn) the sister of Helios (Sun) and Selene (Moon) as well as having heroic identities. http://www.theoi.com/Titan/AstraPlaneta.html

The mother of Hermes is a good example. She was Maia, a daughter of Atlas, she had a mountain (Cyllene) but she was also part of a constellation (Pleiades). She did not die, she was a goddess who left the Earth because she was pursued by the lustful Orion. It's said that Virgo (Justice=Dike/Astraea) was the last goddess to dwell on Earth before the Age of Bronze drove her off. They'd still be watching from the sky, but they wouldn't have to interact.
